|Question: Can I
join lengths of Cat5 using an RJ45 coupler?
Yes. Joining two or more lengths of Cat5 cable using an RJ45
coupler will work just fine, but it should be considered a
temporary solution to whatever connectivity issue required the
use of it in the first place. The more "connection points" that
you have in a cable, or in a network for that matter, provide
additional points where signal loss can occur.
If you must join Cat5 cable using a coupler,
make sure to rectify the problem with a proper length cable as
soon as possible to restore maximum performance to the device
Also, it should be noted that if you are
operating a (speed) certified network, you are not going to be
allowed to have any coupled repair points in the network to
begin with. If you absolutely must have a temporary run of cable
using a coupler, be sure to mark it in an obvious manner so that
it does not get overlooked for replacement.
The use of couplers should always be
considered an emergency measure, such as when a cable is
accidentally severed and the cable cannot be immediately
replaced. In such an instance, a new run of cable should be made
as soon as possible to avoid loss of signal and poor
